If you read the questions when using 'cmake -i .' one of them is what type of build to do: ...Debug | Release ... etc. Default is NONE. So you set that to 'Release'. Then later there is a question about what CXX flags the compiler should use when making a 'Release' build. Default is already '-O3 -DNDEBUG'. I just changed this to '-O3 -march-tbird-athlon' to suit my machine. That's it!
